Look at the reviews for overclocking cards out there such as the 8800GTX. Increasing memory speed gives far less performance increase than increasing the core or shaders.

The fact that ATI was able to use the same core across GDDR3 (4850) and GDDR5 (4870) suggests that the actual bandwidth needed for the processing power probably lay somewhere in between what the 4850 and 4870's bandwidths were. Doubling the processing power means it should still be fine with the memory bandwidth given
lol. did you see the word theoretical. it depends on what you are doing but more bandwidth is generally better.

the reason you dont see a huge increase from ocing memory is because memory doesnt oc well. try cutting your memory speed in half and run a benchmark.

your 4850/4870 argument doesnt make any sense considering how much slower the 4850 is.
